Solid-liquid equilibrium measurements for the ternary system PCL + chloroform + nonsolvents (n-hexane, ethanol, methanol, isopropanol) at 303.15 K

摘要: This work reports experimental data of polycaprolactone (PCL) polymer solubility in chloroform as solvent and n-hexane, methanol, ethanol isopropanol nonsolvents, at atmospheric pressure (about 1,0 bar) temperature 303.15 K. It was used PCL with 70000-90000 2000 molar mass (MM). The experiments were performed using a jacketed-cell controlled by an ultrathermostatic bath, which turbidity method adopted used. From the obtained results it should be observed that n-hexane presented more pronounced anti-solvent effect solubility, where heterogeneous region (solid phase presence) broader than when other nonsolvent. also binodal curves measured high showed similar compared to low one.
